As shown in Fig 2, only CXCL-13 and CCL-24 in both peripheral (p = 0.01 and <0.0001, respectively) and placental (p = 0.01 and p = 0.02, respectively) plasma were associated significantly with maternal anemia in PM+ women when compared to the healthy controls. The gene discussed is CXCL13; the disease is anemia (phenotype).
